The carts are in the printer, the printer needs the carts; no logic to taking 
them out, unless you have a second type of ink you are using alternately, 
which is not at all practical. The whole system is like a living creature that 
has a minimum calorie usage to remain healthy; ink gets used just keeping things 
going. So its not just a number of prints, its a minor investment in just 
keeping the system up. Taking the system down is a bit of a risk as well, since 
unplugging the printer and using no ink requires enclosing it in a plastic bag 
(without lifting it up, and possibly knocking the heads off their sealed 
locations!) with a wet sponge in a plastic tray to assure its a moist environment 
and the heads won't dry out. 3800 carts are intentionally smaller, so that they 
won't remain in the printer for years, the way larger Epson carts do when you 
don't print much. 3800 ink costs less per print than smaller models, so if 
you can afford to print with an Epson at all, you can probably afford to do it 
with a 3800, if you do enough of it in the course of a year or two.
